Inj musc/fasc/tend at shldr/up arm, left arm, sequela

This code signifies a long-term or late effect of an injury to muscles, fascia, or tendons in the left shoulder or upper arm, excluding rotator cuff, biceps, or triceps injuries. These sequelae can include chronic pain, weakness, limited range of motion, or other persistent functional deficits resulting from a previous trauma.

Apply this code when documenting a patient presenting with residual symptoms or conditions directly attributable to an old injury of unspecified muscles, fascia, or tendons in the left shoulder or upper arm. This is appropriate when the acute phase of the original injury has passed, and the current encounter addresses the lasting consequences.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, muscle weakness).
• Ensure documentation clearly links the current condition to a past injury of the specified anatomical site and tissue type.
• Verify that the injury is not to the rotator cuff, biceps, or triceps, as those have more specific codes.
